How many moles of {eq}MgCl_2 {/eq} are present in 50.0 mL of a 0.155 M {eq}MgCl_2 {/eq} solution?
Question:
How many moles of {eq}MgCl_2 {/eq} are present in 50.0 mL of a 0.155 M {eq}MgCl_2 {/eq} solution?
Molarity :
The molarity is a quantitative measure of concentration that shows the number of moles of solute dissolved in the volume of solution in liter. The number of moles gives the mass of solute divided by the molar mass of solute.
{eq}Molarity=\frac {Number of moles of solute}{volume of solution in liter} {/eq}
